GRADING AND DITCHING MAC'HINE.

SPECIFICATION forming part of Letters Patent No. 518,905, dated April24, 1894.

Application filed October 31, 1893. Serial No. 489,654. (No model.)

.To all whom it may concern:

Be it known that I, WILLIAM H. TIDLAND, a citizen of the United States,residing at Nicollet, in the county of Nicollet and State of Minnesota,have invented a new and useful Grading and Ditching Machine, of whichthe following is a specification.

My invention relates to improvements in road-making or grading-machines;and has special reference to certain new and useful improvements uponthat construction of similar machine illustrated in United States PatentNo. 291,427, granted me January 1, 1884..

The objects of my present invention are to provide for a new andimproved mode for handling and adjusting the plow; to provide means forraising and lowering the excavating or ditching-wheel; to improve thecups and the mode of securing the same upon the ditching-wheel andoperating said cups; to provide for an adjustment of the dumpingwheel,whereby the cups are caused to operate for the purpose of dumping at adesired distance from the plow; and to provide for a raising andlowering of the ditching-wheel whereby the same is thrown into and outof operative position.

With these and certain other minor objects in View the inventionconsists in certain features of construction hereinafter specified andparticularly pointed out in the claims.

Referring to the drawings:Figure 1 is a perspective View of a machineembodying my improvements. Fig. 2 is a top plan view. Fig. 3 is atransverse vertical sectional view. Fig. 4 is a detail in perspective ofa portion of the rim of the ditching-wheel together with 7 some of thecups.

Like numerals of reference indicate like parts in all the figures of thedrawings.

In the practice of my invention I employ a substantially semicircularframe 1, which at one side or at its ends is connected by thelongitudinal frame-bars 2, which in turn are suitably braced at pointsdesired. In front and rear bearings between the beams 2 I swivel frontand rear caster-wheels3. In the beams 2 I also locate a pair oftransversely disposed cranked-shaped rock-shafts 4, c0nnecting saidshafts by means of a pair of plow-beams 5. To the lower ends of theseplow-beams I secure an ordinary side-plow 6, whose moldboard is towardthe interior of the framework. It will be obvious that through themedium of the lever 7 which is pivoted at the inner side of the innerbeam 2, the said'plow-beams may be raised and lowered, and by reason'ofthe fact that they are connected to two similarly cranked rockshafts,the bottom of the plow, that is the point and heel, will also be on thesame level whether the plow be elevated out of operative positionorlowered into operative position. Any means may be employed for givingmotion to the plow, and in the present instance, as seen, I pivot thelever 7 to alocking standardz8 providing said lever with a lockingpawl 9for engaging the standard.

At the front of the beams 2 I locate a seatstandard 10, which supports aseat 11 for the accommodation of the driver, it beingunderstoodthat thedraft-mechanism is applied at the front end of the machine, as shown. Inrear of the plow, or rather immediately above the same, I locate asecond standard 12 which supports a seat'13 for the accommodation of theoperator who is positioned at this point for the purpose of manipulatingthe levers and other devices of adjustment heretofore and hereinafterdescribed.-

The opposite side of'the semicircular frame 1 is provided with a.cross-bar l4, and the same, together with the frame 1, accommodates atransverse axle 15, upon which is mounted for rotation a ground-wheel16. A standard 17 rises from the front side of the frame 1 andterminates in an eye, and at the rear side of the frame 1 a pair ofstandards 18 rise and accommodate a winding-shaft 19, at whose inner endor adjacent to the seat 13, there is located a lever 20 or otherwindingdevice by Which means the shaft 19 may be oscillated. A chain 21is wound upon the shaft 19, and at its free end is secured at the rearend of the frame 22. An oblong frame 22 is located in the semicircularframe'l, and at its front end is provided with an eye 23 which engageswith the eye at the upper end of the standard 17. The rear end of theframe 22 is also provided with an eye, and in the same is'coupled thelower end of the chain 21.

By means of the eye 23 being coupled with the standard 17, it will beseen that the rear end of the frame 22 is capable of raising andlowering, which raising and lowering I accomplish through the medium ofthe lever 20 operating the shaft 19 to wind the chain thereon or pay thesame therefrom. The frame 22 is held a proper distance from the plow bythe bar 22, pivoted to the frames 22 and 1, as at 22. Opposite bearingsare arranged in the upper and lower sides of the frame 22, and in thesame is mounted for loose rotation an inclined shaft 24. This shaft 24:serves as the axis of the ditchingwheel 25,which as shown, is a largewheel located in the frame 1 and extending from the outer edge thereofto a point adjacent to the moldboard side of the plow. The rim 26 of thewheel 25 is provided at intervals with bearing-eyes 27, and passingthrough the same is a rod 28. This rod 28 forms a bearing for a seriesof longitudinally curved, hinged or pivoted dirt conveying cups 29,which radiate toward the center of the wheel and normally lie upon thesame. Each of these cups is provided at its inner end with an eye 30,and passing through the eyes of the series is a loose slat connectingchain or belt 31,whereby the entire series of cups is connected. Thebottom of the wheel, it will be seen, travels upon the ground-wheel 16at one side and being inclined, as shown, at its opposite side or thatside adjacent to the plow, travels upon the ground, so that as themachine is drawn along the wheel 25 is revolved by reason of its contactwith the ground and the said wheel 16.

Acurved track 32 extends from the rear end of the frame 22 concentricwith the shaft 2a thereof to a point near the front end of the frame 22,and then abruptly bends outward and downward forming a standard 33,whose lower end is fastened to the semicircular frame 1. Aswinging-arm34: is pivoted at its inner end to the upper end of the shaft 24:, andat its outer end is bifurcated, as at 35, and accommodates a verticalpin or journal 36 upon which the dumping-wheel or disk 37 is mounted. Ayoke 38 of U-shape has its terminals connected with the track 32, passesunder the dumping-wheel 37, and forms a lower additional bearing for thejournal-pin 36. This yoke is designed to travel upon the track 32 andaid in supporting the arm 34 upon the track. The arm is also providedwith an eye 39 upon its upper side, which loosely engages with the track32. By this means the dumping-W11 eel is located and supported above theperiphery of the wheel 25 and slightly inside the same, and inasmuch asthe series of connected cups pass over the wheel 37, it will be seenthat each is successively brought to a vertical position, to dump itscontents upon the ground at such a point as maybe regulated by theposition of the wheel 37 In order to provide for a convenient adjustmentof the wheel 37 I connect with the journal-pin thereof a curved rod 40,which terminates at one end in a handle 41, and

passes through a guide-eye 42 formed in a guide-standard 43 which risesfrom the frame 22, the handle being in easy reach of the operator whenmounted upon the seat 13. A pair of hangers 4C4: depend from the upperframe-bar of the frame 22 at the upper end of the same, and in the lowerends thereof is journaled a depressing-wheel 45 which travels over theseries of cups, depressing them upon the wheel 25 as they leave thedumpingwheel 37 whereby they are forced back positively to theirrefilling positions. This completes the improvements upon myformerconstruction, and it will be seen that I provide, as before statedas being the objects of my invention, first, a convenientmeans forraising and lowering the plow; second, a convenient means for raisingand lowering the ditching-wheel; third, a convenient means of attachingthe cups to the ditching-wheel; fourth, means for' adjusting thedumpingwheel, whereby the latter is caused to dump the dirt at a desireddistance from the plow which is forming the ditch; and, finally, Iprovide for a depression of the cups afterthe same have dumped and areabout to be refilled.

The operation of the machine, it Will be understood, is similar to thatdescribed in the previous patent heretofore referred to and may bebriefly stated as fo1lows:-The ma chine is drawn along with the plow atthe side of the road,said plow forminga ditch, as will be obvious, andthe soil turned up by the moldboard of the plow is deposited upon thecups as they are successively brought adjacent to the plow. These cupsare carried by the wheel 25 and are successively operated upon by thedumpingwheel, or in other words, are elevated and their contentsdischarged from the machine at any point of the road, the point beingvaried in accordance with the width of the road and the desiredconvexity of the road-bed in a manner obvious. I

I do not limit my invention to the precise details of constructionherein shown and described, but hold that I may vary the same to anydegree and extent within the knowledge of the skilled mechanic.
